+## Plot the filled contour lines of a function.  @var{f} is a string, inline
+## function or function handle with two arguments defining the function.  By
+## default the plot is over the domain @code{-2*pi < @var{x} < 2*pi} and
+## @code{-2*pi < @var{y} < 2*pi} with 60 points in each dimension.
+##
+## If @var{dom} is a two element vector, it represents the minimum and maximum
+## value of both @var{x} and @var{y}.  If @var{dom} is a four element vector,
+## then the minimum and maximum value of @var{x} and @var{y} are specify
+## separately.
+##
+## @var{n} is a scalar defining the number of points to use in each dimension.
+##
+## The optional return value @var{h} is a graphics handle to the created plot.

+## @example
+## @group
